We have created an integration of freshchat with instagram and for that, we have made a developer application on Facebook. Our FC app is configured with OAuth 2.0.
The Issue is when we install the app on Freshchat, the pop up which opens up to authenticate Facebook shows blocker as shown in the screenshot
The developer app is working fine as if we paste that same URL from the popup on a new tab on our browser, it works fine so this looks like an issue within freshchat app.
Facebook has been rejecting our developer app due to this issue and because of that, we are unable to submit our app causing us a blocker here.
Can you please identify and let us know the resolution ASAP.
